Abstract

Système de mesure photométrique de la concentration d'un ou plusieurs constituants d'un mélange gazeux. Les filtres de mesure sont régulièrement répartis sur un disque tournant à vitesse constante 28. Un faisceau lumineux axial 172 traverse une sonde perforée 21 plongée dans le mélange, et il est réfléchi par un miroir 27 situé à l'extrémité de la sonde Un photomultiplicateur 50 fournit un signal multiplex correspondant aux impulsions de sortie des filtres qui interceptent successivement le faisceau réfléchi 173. Un tube perfore monté dans la sonde permet d'établir une circulation d'ozone pour le dosage de NO par transformation en NO2 , N2 O 5 n'apparaissant pas en raison de la vitesse des gaz. Dosage de SO2 , NO, NO 2 et H2 S dans les fumées dumées de chaudière ou fours de récupération.System for photometric measurement of the concentration of one or more constituents of a gas mixture. The measurement filters are regularly distributed on a disc rotating at constant speed 28. An axial light beam 172 passes through a perforated probe 21 immersed in the mixture, and it is reflected by a mirror 27 located at the end of the probe A photomultiplier 50 supplies a multiplex signal corresponding to the output pulses of the filters which successively intercept the reflected beam 173. A perforated tube mounted in the probe makes it possible to establish an ozone circulation for the determination of NO by transformation into NO2, N2 O 5 n ' not appearing due to gas velocity. Determination of SO2, NO, NO 2 and H2 S in the flue gases from boilers or recovery furnaces.
